DEA, Fast and Furious, and the AZ Gabrielle Giffords & Judge John Roll shooting

This guy says that Gabrielle Giffords and Judge John Roll were shot because they were investigating Fast & Furious...

"Wayne Madsen has learned from his contacts within the Beltway intelligence community that Jared Lee Loughner is an “MK-ULTRA” programmed assassin and that US District Judge John Roll and Congresswoman Gabriel Giffords were targetted for assassination.  The reason for the decision to target Judge Roll and Congresswoman Giffords has to do with their knowledge of the malicious and purposeful arming of Mexican drug gangs along the US-Mexico border by US intelligence agency assets"
